Distribution Power Quality Improvement Using Impedance Source Inverter (ZSI)

摘要

Power quality plays an important role while transferring power to maintain uninterrupted and continuous supply to the consumer. Voltage sags, voltage swells, flickers, etc., are the common problems which degrade the power quality. So, this paper presents one of the means to overcome this, by including FACTS devices like ZSI (Impedance source inverter) based STATCOM in the network. The device is controlled using proposed unipolar and bipolar PWM techniques. The proposed methods can be used to overcome the disadvantages of the existing devices. Simulations of the proposed circuitsare shown and it is done using MATLAB/SIMULINK software.
